The work aims to design and develop a kind of auto-hot stamping machine for bottle-caps to reduce the labor intensity, ensure a safe operation and improve the product quality. Through the analysis and discussion on the status quo of the bottle-cap hot stamping technique and equipment, the overall plan of machine was constructed and the work process was set up. With the help of SolidWorks and Caxa software, the composition and structure of the machine were designed and verified. By improving the feeding mechanism, the requirements of feeding speed and feeding quality of the cap were met. Through the optimization of such key components as conveying mechanism, transfer scalding head and running mechanism, the conveying precision and the bronzing quality of the cap were ensured. The application indicates that the machine is featured by reasonable design, compact structure, high efficiency, safe operation and stable and reliable running.
